Final answer:
In the reverse reaction of C + H2O = CO + H2, the products would be carbon (C) and water (H2O).
Step-by-step explanation:
The student is asking about the reverse reaction of C + H2O = CO + H2. In the reverse reaction, the products of the original reaction become the reactants. Thus, for the reverse reaction, carbon monoxide (CO) and hydrogen (H2) would combine to form the original reactants, carbon (C) and water (H2O). Therefore, the products of the reverse reaction would be carbon and water.
